A new class of bis(oxadiazolyl/thiadiazolyl/triazolylmethyl)sulfones were prepared by the cyclocondensation of sulfonyldiacetic acid with aryl acid hydrazide and arylmethanesulfonylacetic acid hydrazide.

experimental part, p. 2106 - 2112 (2009/09/25)
A new class of 1,3,4-oxadiazoles were prepared from acid hydrazides on treatment with different carboxylic acids in the presence of phosphorus oxychloride. Interconversion of oxadiazoles to thiadiazoles and triazoles was carried out with appropriate reagents. The antimicrobial and cytotoxic activities of compounds 7a-d to 12a-d were tested. Compounds 10d and 12d showed pronounced antimicrobial activity. Further, compound 10d exhibited maximum cytotoxicity.

A new class of five membered heterocycles, thiadiazoles, triazoles and oxadiazoles were prepared from sulfonyl acetic acids via acid hydrazides.
Sulfonyl acetic acids - Source for substituted 2-oxazolines
Padmavathi,Reddy, B. Chandra Obula,Subbaiah, D. R. C. Venkata,Padmaja
, p. 2456 - 2458 (2007/10/03)
A new class of 2-oxazolines have been prepared from N-(2-chloroethyl) sulfonamides by base promoted cyclization with NaH in THF. All the compounds are characterized by IR and 1H NMR spectra.
Sulfonyl Esters. V. A Preparation of Dichloromethyl Sulfones
Langler, Richard Francis,Steeves, Jennifer Lea
, p. 1641 - 1646 (2007/10/02)
α-Sulfonyl methyl esters have been chlorinated in the presence of base.Chlorination proceeds with accompanying demethoxycarbonylation to furnish dichloromethyl sulfones in good yields.
Intramolecular rhodium carbenoid insertions into aromatic C-H bonds. Preparation of 1,3-dihydrothiophene 2,2-dioxides fused onto aromatic rings
Babu, Suresh D.,Hrytsak, Michael D.,Durst, Tony
, p. 1071 - 1076 (2007/10/02)
The preparation of 1-carboalkoxy-1,3-dihydrobenzenothiophene 2,2-dioxides via rhodium acetate or rhodium trifluoro-acetate catalyzed decomposition of α-diazo-β-arylmethanesulfonyl esters is described.The reaction has been extended to yield 1,3-dihydrothiophene 2,2-dioxides fused to the 2,3 position of thiophene and indole, but not of furans.In the latter case products derived from the opening of the furan ring were obtained.Key words: synthesis, 1-carboalkoxy-1,3-dihydrobenzothiophene 2,2-dioxides, intramolecular carbenoid insertions, rhodium acetate catalysis.
